The under rail portion of the anchor functions as a resilient lever to exert the combination leverage'or tilting pressures above referred to. The fit of thej aw member on the rail base is preferably such that the said'resilientleverage doesno't produce any substantial tilting about the traiisverseaxis, but the tilting pressure exertedforms a partof the combination gripeflected and adds to the tenacity of its hold on the rail. 5

In applying'the anchorito a rail base flange, the jaw member is slipped over the 'rail'flange which it is intended to hold and forced on by hand as far as it Will go. The anchoris then struck. on the arm'12 or bend 13 adjacent the jawl2 with as'pike maulbr sledge, whereby the portion l2 is driven upon thebase flange embraced and the bodymember 1 yields and elongates. Thisoperation is continued until I the verticaledgesengaging means 3 clearsthe opposite edge of the-rail base flange and snaps into position; The anchor may also be forced to .its applied position by pulling outwardly on the end 30f the anchor until the portion 3 clears theedge of the rail base whereupon the resiliency ofthebody will cause the portion 3 to snap over the'edge of the railbase into locking engagement with the vertical edge surface of the rail base.

Due to the construction of when in positionon a rail base flange, it exerts a transverse pressure at9 and 7 an upwardpressure at 5 and 11 and a downward pressure at 4. The transversepressure pro vides an efiective grip to hold the jaw end of V the anchor on the rail. The bowed construetion of the under vrail portion provides for sufficient resiliency to permitfthe anchor to be easily sprung to its locked position on the.

rail and also permits application of the anchor to base flanges of different base widths.

In the modification illustrated in Figurefi,

the body member is shown curved differently from that illustrated in Figuresl toe. In

this modification the body member lhas dis; posed at the opposite ends thereof a jaw. 2

and a vertical edge-engaging means 3 which are similar to those disclosed inmy preferred embodiment. The body member 1, however, differs from the body member, 1 in that, when the jaw member isjapplied to the same base 4 flange as the jaw member shown in Fig.3,

of said jawp'ortion.

this anchor,

the body is curved rearwardly adjacent the jaw member 2 and forwardly adjacent the flange-engaging means 3 forming a substantially S-shaped loop having the rail flangeengaging means on the opposite side thereof.

Inthis anchor, due to the curvature of the body member 1, the rail base flange-engaging means 2 and 3 are oifset to each other and disposed in different vertical planes. As

in the preferred modification, the j aw 2handpthe armv 11; are disposed *in planes higher than that occupied'by the small jaw 5. The

manner or mode of'application is the same as that employed in applying the preferred modification.

Since it is obvious that various modifica: tio'ns may: he made without departing from Ithe naturefof. the inventioml I do not limit myself to the exact'and specific details above described except as hereinafter claimed.

5. A rail anchor formed from a flat metal plate and comprisin a laterally disposed U-shaped body member, a "jaw presenting edgewise or cross-section contact with the vertical edge of a rail base flange which itis adapted to engage disposed at one end of said U-shaped body member, vertical edge-engaging means disposed at the other end of said U-sha-ped member and adapted to engage with-its flat side surface the vertical edge of a rail base flange. 6. A rail anchor formedfrom a flat metal .blank recessed to receive the base portion of and provided with a bottom bearing portion adjacent said edge engaging means for bearling against the bottom surface of the rail base,

the said body portion being bowed laterally relative to the side plane of said aw portion to provide resiliency both vertically and transversely of the rail and the bottom bearing portions at opposite sides of the rail being so disposed with relation to each other R that the last mentioned bottom bearing is forced downwardly to a position of substan tial alignment with the first bottom bearing,

in applying the anchor to a rail.

7. A rail anchor formed froma flat metal blank and comprising a'body provided at one end with a jaw portion disposed edgewise to one base flange of the rail and including a jaw for gripping the top of one base flange,

and at the other end with means for engag ing the edge portion of the other base flange; the said body portion being bowed laterally relative to the side plane of said jaw portion and adapted to press upwardly against the bottom of the rail base at a point remote from said jaw portion to hold the jaw portion turned about an axis extending longitudinally of the rail and in a direction tending to force the inner end of said jaw into tight gripping engagement with the top surface of the rail base flange engaged.

8. A rail anchor formed from a flat metal blank and comprising a body formed at one end with a jaw portion disposed edgewise to one base flange of the rail, and at the other end with means for engaging the edge portion of the other base flange; the said body portion being bowed laterally relativeto the side plane of said jaw portion and adapted to press upwardly against the bottom of the rail base at a point remote from the said jaw portion to hold the aw portion turned about an axis extending longitudinally of the rail and to also exert a force on said jaw portion tending to tilt it about an axis extending transversely of the rail base.
